i made a folder in the custom story folder and saved it and i have placed all the necessary folders in my custom story but everytime i go into the game to load up my custom story, its not there.
can someone please explain what i might have done wrong?

Maybe your config files aren't properly formatted. Make sure to enable extensions and check if it's not .cfg.txt. Otherwise make sure it's also pointing to an existing map, or else it will not show up either.
